Hello Simon, hello together, I am not a native english speaker. Please forgive me for grammatical errors. 🙂 Have a 42LM640S with followed Problem: The SETTINGS will not works and if i push the HOME Button or MY APPS Button or INPUT: with all Buttons will show on TV only on right Corner below a red circle with message : loading. But nothing will happen. The TV has got the Firmware 4.62.12. The old Firmware from LG Homepage 4.40.19 will be denied. There ist also no chance to start the systemmenu like SETTINGS to try to reset or other. My only way to update or downgrade will works with USB or network. I can watch TV without errors, but all other functions are gone. NOW my Question: how can i downgrade under this Circumstances my lovely TV? How can i fix it? I hope for answer and that you understand me :-) . The LG support cant help me. 😞 @SIMON I checked your tutorial and everything looks good until point 9. Maybe do you have a solution for me?
